n i Specification of Letters Patent. Patented J n 1 1915 Application filed March 20, 1915. Serial No. 15,916.

lowing to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to 4 makeand use the invention, reference being being broken away. Fig. 2 is a longitudinal had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is a vertical transverse section of the engine on the line 1-1, Fig. 3, parts section on the line 2-'2 Fig. 3, parts being broken away. Fig. 3 is a horizontal section, on the line 33, Fig. 1.

The invention has relation to rotary valves for explosive engines, and it consists in the novel e. construction and combinations of parts, as hereinafter set forth.- I v In the accompanying drawings, illustrating the invention as applied'to a four-cycle engine,'the numeral l designates the work-' .ing' cylinder. of the engine, 2 the working piston and 3 the crankshaft, having an operating rod connection 4 with said piston.

Each cylinder is provided atone side with adjacent cylindrical valvev chambers 5, 5', for inlet and exhaust respectively, and in each valve. chamber works a rotary cylindrical valve .6, having means for turning the same,

' preferably worm gear 7, provided with a chain connection 8 with the shaft 3, the

valve being thereby.'turned once around for each two revolutions of the crank shaft.

The valvechambers arranged in pairs are provided one with an inlet opening 9' to the cylinder and the other with an'exhaust openv y 'In an explosive engine, a crank chamber,

parallel adjacent valve chambers, a lower ing 9 leading from the cylinder. Each valve is open at one end at 10, and has a cylindrical side wall 11 in which an inlet or exhaust opening 15 or 15 is provided. The inlet pipe 11, has connection with the-openend of the inlet valve, and the exhaust pipe 12 has connection with exhaust valve. 1 j

The working cylinders connected up in multiple, as in fours, are provided with a carbureter 13, with whichthe inletpipe has connection, said inlet pipe having oppositely extending branches 14;, 14, each the-"open end of the working cylinders. The exhaust valves of said adjacent cylindersare located upon the outside of the adjacent inlet Valves, being connected with a single exhaust main 15 by the pipes 12.

The inlet and exhaust pipe connections with the open ends of the valves are located at' substantially right-angles to each other,

the intake extending upwardly and curving over the top of the valve towhich it leads.

The worm gear 7 for each valve comprises a vertical valve shaft 6, located in a chamher 5 below the valve chamber and provided with a horizontal partition'l7 between the same and the crank chamber, said shaft I having journal hearings in a perforation 18 of said partition, and carrying at its lower .end the worm gear, whereby any surplus oil from the valves will drain into the crank chamber.

branch being subdivided as at 11 and lead ing to the adjacent inlet valves of adjacent The waterjacket for the working cylina v der' and valve cylinders is shown at 16.

My engine is of simple construction, the valves-are inclosed and silent in their operation. The engine is easy running and the valves capable of rapid operation without.

undue wear, whereby the p0wer o the engine-is increased and the vibrat on'ther'eof lessened, the intake and exhaust having both free fassage. Th parts being surrounded by e. cient water jackets, the valves are fire vented from becoming unduly heated.

What I claim is:

inlet and exhaust openings in the lateral walls thereof, said valves having open upper ends, and shafts located in said lower chamber and having journal bearings in crank shaft and the shafts of the rotary valves, including woi rn gearing and a sprocket chain connection between the crank 10 shaft and the worm shaft.

In testimony whereof I afiix my signature,

in presence of two witnesses.
